Thermionic energy converters are heat engines that convert heat directly to electricity at very high temperatures. A basic thermionic converter consists of two electrodes separated by a vacuum or a vapor. In 1915, Schlichter published an investigation into the use of thermionic emission for converting heat into electricity.
